IT IS GRATIFYING TO MAKE RECORD ALSO OF THE FINANCIAL AID CONTRIBUTED TO THE PUBLICATION OF THIS PRIMER THROUGH A GENEROUS PERSONAL BEQUEST TO THE AUTHOR FROM THE LATE MRS. MARY E. GARST SMITH OF NORTH BROOKFIELD, MASS., WITH AN EXPRESSION OF HER HOPE FOR ITS USE ON LINES WITH WHICH THIS WORK IS IN ACCORD. Transcriber’s Notes Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in the original book; otherwise they were not changed. Simple typographical errors were corrected; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced.
